<p>An airway clearance system (10) and method produces high frequency chest wall oscillations (HFCWO) and increased airflow velocities through the air passages to clear the lungs of mucus. The system (10) includes a chest wall force applicator (12a) to produce the HFCWO and an air pressure input mouthpiece system that enhances airflow to and from the patient's lungs. The system (10) and method can be adjusted to cancel a bias line force component, measure airway resistance and induce a cough.</p> |
